Brqke Fluid Chonge
The broke f luid obsorbs otmospheric humidity
ond the chcnge of its properties
is opt to offect
broking ond even bring obout corrosion of some
ports of the broke system.
The time period,
in which these chonges
con
toke ploce,
connot be defined with ony pre-
cision. Therefore forestoll troubles ond chonge
the broke fluid in the broke ond clutch system
every few yeors (preferobley
two to three
yeors ) .
Suck out the old f
luid from
the tonk, fill in
fresh fluid, ond remove the bleeding screws
one
ofter onother to let the old fluid be forced out
by the fresh
one from oll bronches of the broke
line to the clutch -
see the broke ond clutch
bleeding procedure.
Broke Bleeding Air con get
into the hydroulic system
of the
brokes either due to lock
of the broke fluid in
the tonk (low
level) or when removing
or dis-
montling some ports
of the hydroulic line. lf
there is o smoll omount of oir in the hydroulic
system, the pedol broke feels "spongy"
ond the
broke efficiency decreoses. Ingress of o lorge
